I had a similar question. We typically have to shutdown and clean our dies every 2-3 days because of plate out issues. Running foamed PVC sheet. We had issues with burning, but since adding more processing aid, and a little more lubricant that issue is not as bad. However we have build up on the lips and behind the restrictor bars that cannot be cleaned without opening. Is there a way to clean, or "scrub" the dies without shutdown and during a run without breaking the sheet?
